船舶三维导航系统综论

A Comprehensive Review on the 3D Ship Navigation System

船舶三维导航系统集船舶信息采集系统、信息数据融合处理系统和三维可视化系统于一体。系统以信息交换和共享支撑平台为核心,以海量数据存储和处理、电子航道图管理和应用、三维虚拟仿真计算等为关键技术,指导船舶按照预先设定的航线航行。航行过程中,实时对实际航线与设定航线进行比对,得到航向偏离和轨迹偏离的警示,以提高航行精确度;实时显示船舶状态和航道状况,并高亮显示桥梁等障碍物,以提高航行安全性。船舶三维导航系统形成了三维模型、场景、交互的成套解决方案,对航海领域的高科技应用具有重要作用。

3 D ship navigation system is an organic combination of ship information collecting system,ship information data fusion processing system and 3 D ship visualization system. The system takes the information exchange and the sharing support platform as the core, and uses the key technologies including massive data storage and processing, electronic channel map management and application, and the 3 D virtual simulation, as to guide the ship navigation as per the preset route. In the navigation process,the actual route is compared with the set route in real time, so that the deviation of the origination and the track are obtained to improve the navigation accuracy. Also, the state of the ship and the condition of the channel are displayed in real time, and especially, the obstacles such as the bridge are highlighted, as to improve the navigation safety. The 3 D ship navigation system has formed a complete set of solutions for 3 D models, scenes and interactions, which is of great significance for the modernization and high technicalization of navigation support.
